40 series tires for Revo?

[Dafni]

My advice is to stay away from them, especially on a Revo. They make you pop your knuckles off the pillowballs very easily, and they eat up knuckle bearings much quicker. When I got sick of popped knuckles and upgraded to alloy knuckles the bearing headache sarted... regular wheels solved those problems (to an extend)
This was like 3 years ago, before we had those narrow truggy wheels. If you want a "precise" tire, go the truggy way.

Just my opinion and experience.
